Description: The Mössbauer study of <math>^{57}Fe\,\!</math>: <math>YBa_2Cu_30_{6+\delta}\,\!</math> oxides was very important to establish the preferential occupation of Cu(1) site by Fe at very low concentrations. Recent determination of antiferromagnetic ordering for Cu moments in Cu(2) sites (T <math>\sim\,\!</math> 450K) and our early observation of a small proportion of a magnetic phase at room temperature for <math>Fe:YBa_2Cu_30_6\,\!</math> lead us to perform systematic studies of <math>YBa_2(Cu_{1-x}Fe_x)_30_6\,\!</math> with x = 0.005, 0.03, 0.05, 0.10 and 0.15 in order to obtain information about the iron occupation of Cu(2) sites.
